Embodiment Construction

[0017] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0018] Such as Figure 1-3 As shown, the first embodiment of the combined anal expansion introducer of the present invention includes a cylindrical tube body 1 and a fixed seat body 2 with a window 11 on the tube wall, and the axial length of the window 11 is 35 to 45mm. The radial width is 30~40mm, and the cylindrical pipe body 1 and the fixed seat body 2 are connected by threads. One end of the cylindrical pipe body 1 is a hemispherical round head 12, and the other end has an external thread connected with the fixed seat body 2. The top of round head 12 has through hole 13, and fixed seat body 2 comprises expansion pipe body 21 and is arranged on the fixed ...

Abstract

The invention relates to a combined-type anal dilatation gatherer which comprises a cylindrical tube body and a permanent seat body, wherein the wall of the cylindrical tube body is provided with at least one window; the cylindrical tube body is in threaded connection with the permanent seat body; one end of the cylindrical tube body is provided with a hemispherical round head, and the other end of the cylindrical tube body is provided with an external thread connected with the permanent seat body; the top of the hemispherical round head is provided with a through hole; the permanent seat body comprises a diverging tube body and a fixed conical disc arranged at one end of the diverging tube body; One end, back on to the fixed conical disc, of the diverging tube body is provided with an internal thread matched with the external thread of the cylindrical tube body; and the fixed conical disk is provided with an open pore used for fixation. The combined-type anal dilatation gatherer can achieve multiple functions through combination or separation, and meets different surgery requirements; when the anal dilatation gatherer is combined, a doctor can conveniently perform a minimally invasive surgery; and after the anal dilatation gatherer is separated, the permanent seat body can be used for realizing a girdling surgery.

Description

technical field [0001] The invention relates to the technical field of anorectal surgical examination and treatment devices, in particular to a combined anal expansion introducer. Background technique [0002] The soft vein group formed by the expansion and flexion of the venous plexus under the mucous membrane of the end of the human rectum and the skin of the anal canal is called hemorrhoids, also known as hemorrhoids. Hemorrhoids referred to in medicine include internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. It is a chronic disease of one or more soft veins formed by varicose veins at the bottom of the anus and rectum and the anal mucosa. Prolonged hemorrhoids can cause hemorrhoids to prolapse and become incarcerated, aggravating the pain and condition. Secondly, anal infection, once bleeding symptoms of hemorrhoids form, bacteria, toxins, and pus plugs can easily invade the blood and cause sepsis. In addition, due to the prolapse of hemorrhoids, the s...
